3.5.7 Port 6 (P60 - P67)
Port 6 is an 8-bit general-purpose I/O port. I/O can be set on
bit basis. Resetting sets Port 6 as an input port and connects
a pull-up resistor. It also sets all bits of the output latch to 1. In
addition to functioning as a general-purpose I/O port, Port 6
also functions as a pattern generator PG0/PG1 output. PG0 is
TOSHIBA CORPORATION
assigned to P60 to P63; PG1, to P64 to P67. Writing 1 in the
corresponding bit of the port 6 function register (P6FC)
enables PG output. Resetting resets the function register
P6FC value to 0, and sets all bits to ports.
